ABSTRACT:
The invention is directed to a mechanical control unit for a supporting stand for a surgical microscope. The mechanical control unit constrains the surgical microscope to move along the surface of a sphere about the point at which surgery is performed when spatially moving the microscope. In this way, the focusing adjustment of the surgical microscope onto the point of surgery is maintained for each viewing direction. The mechanical control unit is connected via adaptation positions to the supporting stand which is translationally movable in three spatial directions and is rotationally movable about three axes.
